Prorated Rent Calculator
When a lease starts or ends mid-month, rent is normally prorated. Different leases use different daily rates, so the method matters as much as the arithmetic.

12 days at $73.33 per day.
- Daily rate used

Same period under each method
| Method | Daily rate | Amount owed |
|---|---|---|
| Actual days in month | $73.33 | $880.00 |
| 30-day month | $73.33 | $880.00 |
| 365-day year | $72.33 | $867.95 |
What this means
Using the actual days in month method, 12 days of occupancy costs about $880.00.
Leases should state the proration method. If yours does not, ask before signing — the difference between methods is usually small but it is real money.
How this calculation works
- Days-in-month method divides monthly rent by the actual number of days in that month.
- Banker's method divides by 30 days regardless of the calendar month.
- Annual method multiplies rent by 12 and divides by 365, producing the most consistent daily rate.
All results are estimates based on the assumptions you enter. RE View does not provide financial, tax, or lending advice.
